Lower the batch size first, and use gradient accumulation to keep the effective batch size the same by adding up gradients over several smaller batches. Turn on mixed precision with torch.autocast, which roughly halves activation memory on modern GPUs, using bfloat16 where the hardware supports it.

For images, text, and audio, a pretrained model from TorchVision or Hugging Face already knows general features, so fine-tuning reaches good accuracy with far less data, time, and GPU cost than training the same architecture from zero. Training from scratch makes sense when your data looks nothing like what public models were trained on (specialized sensor signals, unusual imaging), when the architecture itself is what you are researching, or when licensing rules out the available pretrained weights.",{"question":560,"answer":561},"When should training move out of Jupyter into scripts?","Once a training run takes longer than you want to babysit. Notebooks are the right place to explore data, check shapes, and debug a model on a few batches, but a long run inside a notebook dies with the kernel or the browser connection. Move the model, data loading, and training loop into Python modules with a command-line entry point, read hyperparameters from a config file, and set random seeds so a run can be repeated.
